OCN Practice Test

Prepare for your test with realistic questions.

The Oncology Nursing Certification Corporation (ONCC®) Oncology Certified Nurse (OCN) exam was designed for registered nurses seeking to demonstrate their understanding of current knowledge and practice in oncology nursing and feel the personal accomplishment of earning OCN certification. The OCN exam tests your advanced knowledge and skills related to oncology nursing beyond the minimum knowledge and skills necessary to become an RN.

What is OCN certification?

While RN licensure demonstrates the requisite entry-level knowledge to begin working in the field, it does not necessarily demonstrate to your employers or patients your dedication to continuing your education and broadening your knowledge and skills. The OCN certification process is voluntary and provides your employers and patients with the assurance that you are dedicated to obtaining and maintaining specialty knowledge in oncology nursing.

OCN certification also provides comfort to your patients and rewards to you as an RN. Certification, while voluntary, may be necessary for advancement into higher-level roles in your organization and can help open additional professional opportunities, including potential income increases.

OCN Exam Eligibility

In order to take the OCN exam, you must hold an active, current, unencumbered RN license in a state or territory of the United States or Canada. Potential test-takers must also demonstrate at least one year (12 months) of practice and experience as a licensed RN, occurring within 3 years of completing the application for the exam.

Additionally, you need to have completed at least 1,000 hours of adult oncology practice in nursing within 2.5 years prior to application. This practice needs to have been completed as a licensed RN and can be clinical, educational, administrative, or in a research capacity.

Lastly, you need to have completed at least 10 hours of continuing nursing education in an oncology-related area within the previous 3 years.
